The invention is shown as comprising two uni-ts fixed to a bed 10; This lathe is provided with two supports 11 and 12 spaced apart. On account of the fact that the bering or pin turning' will be donelon' the two 0 a circle and the necessity of getting the mechanism closeto the axial'line of the work,

the supportingdea'dcenters 13 and 145 are offset, one is; shown as ofiset horizontally and the other vertically. By this means the slides supporting the centers can be madesufficiently large to rigidly support thew-501"]: andat tliesame time allow the mechanism to bebreught into sinal-l' compass as will appear. Forquartering the dead centers are offset tht'oughan angle ch? to each other, but" for thirdilig' they are offset through an angle e f-". j y. a

The wlieel s'et' 15"p'referably isisupported ends at points at 90 from each other around on aieks" 16' whichinvolve open-top V-shape' I supports forthe journal, The wheel-set is liftedby a crane or other meansand brought around into position and set on these Vs and then they are adjusted vertically by nuts 17 to bring the wheel-set so that it will be in position to be supported on the two centers 13 and 14. These centers are then moved inwardly and the wheel-set is thus fixedlv mounted and supported on the centers, but its weight can be supported mainly by the jacks. Then two clamps 19 are adjusted and secured to the wheels of the wheel-set to hold the wheel-setagainst turning. Thus the 'lar to a ratchet motion.

work is clamped firmly in position and supported by means which is well understood in this art and'therefore is not described here: in in detail.

It is the purpose of this machine to operate simultaneously on the two wheels either to bore the holes for the pins or to turn the pins, or, if desired, to bore the hole in one'wheel and turn the pin on the other, simultaneously.

The supports 11 and 12 are fixed to the bed and they carry the supports 20 for the centers 13 and 14. One of these is shown in Fig. 3. This center 13is mounted on a cyline drical slide 21 which is provided with a key 22 securedin its side by screws 23 and running in a slot 24 in the support '20 and integral with the center 13.v 'This side of the support is in a vertical plane on this head but in a horizontal plane in the one a the opposite end. The slide 21 is clamped by a wedge 9 loose ona clamping screw25.

For moving the slide it is provided with a screw 26 entering a screw-threaded sleeve 27 fitted in the end of the slide and having on its end a hand wheel 28 for operating it. As the space in which this hand wheel can be located is comparatively small, due to the presence of other members around it, it doesnot pro- .vide enough leverage for the final tighten 111g. 7 29 is mounted on the shank of the screw 26 and is provided with a pivoted handle 30 and a clutch 31 operated by the handle. This handle can be turned to the dotted line position in Fig. 3 and swung to operate the screw and tl'ien disengaged and turned again, simiilt the other end thecenter 14 is offset upwardly, instead'of sideways as on the left hand end, but the mechanism is substantially the same as indi cated in Figs. 12,13 and 14.

At this end a handle 32 extending horizon- V tally projects through a slot 33 in the support- 20 and has a clutch 34 for operating a vertical screw 35 which moves ahead 3611p and down in vertical ways 37 to raise and lower themechanism above. As this mecha nism is substantially the same at this end as at the other end, except for its vertical adfiustment, the other v mechanism has been shown more in detail and the dQSCIIlPtlOHV1ll be applied thereto. 7 I

Referring now againto the left hand as shown in Fig. 1. the stationarysupport 11 also For that reason an oscillating collar supports the tool operating mechanism and this comprises several'parts. On this support is a screw 40 which, by means of a wrench can be turned tooperate a nut 41 constituting a part of a transverse slide 42 so that this slide can be moved toward and from the center 13 which, on account of the center 13 being off-set to the left and its inner surface being-flat and Vertical, the slide 42 can be adjusted comparatively close to the axis of the wheel-set. =This slide 42 has Ways 43 which carry a longitudinally movable slide 44 and this slide has a rack 45 along its side.

With this rack meshes a pinion 46 carried by the slide 44. Thispinion is located on a vertical shaft 47 which, by means of worm and gear 48 is rotatedby a horizontal shaft 49, carrying the worm, for feeding the slide 44 longitudinally and thus moving the cutting tool along the work. This feed may be performed by hand or power.

The hand feed is provided through the shaft 49 on whichis one element 51 of afriction clutch in the form of a hand wheel. The

57 fixed on a shaft 58 mounted in ballbear ings and supported crosswise on the'slide 44. This shaft has a Worm which operates a worm gear 59 arranged axially and operating the boring or-turning'tool. The gear 59 is located in a housing or casing 60 constituting an integral part of the longitudinal slide 44.

It is fired byscrew collars and the like 61- to a hollow tool holder 62 which is mounted to rotate in this casing. The casing 60'has a cyl ndrical integral bearing surface 63, at one end in which the holder 62 is held in position so as to rotate therein and avoid chatter- 'ing while the other end is held in a bearing member 66 provided between the surfaces of the casing and holder, one of its surfaces being conical. On the extreme end of the easing 60 is a flange 64 and gland 65 of ordinary .well known construction to retain the lubricant. This provides forthe' rotation of this tool supportingholder 62. 1 7

It may be stated here that this holder can support tools for turnirg'the exterior of the pins as shown in Figs. 2 and 7. Apair of plates 67 arebolted in T-slots'68 in the end ofthe hollow holder (32 and carry in clamps 69 two cutting tools 70. On the other hand' itcan be used to carry a boring bar 711110111113- ed in a carrier "72 which is also fixed in the T-slots 68." v Q It has been described how this tool holder isrotated"and'adjusted forward and back'by opens and closes was 74 which iscen'tered and fixed lll-tllQBIlClOf the tool holder 62. This gear meshes with a gear 9'4 which :in turn meshes with a gear 7 5 as shown in Fig-f8. The gearB t is on a plate 76 'whihis'adapted to be turned onthe axis of the shaft 77 on'whichthe gear '7 5 is located andthrough-an adj ustment 78thegear 73 can be changed fora gear of adi fferent size to alter'th'espeed.

The gears "justdescribed' are mounted in a gear box98. The shaft 77 extends from the side of this gear box'and is provided with a pair'of sliding gears'79 adapted to be operatetl'by ahandleSO to throw them inor'out of mesh with twoune'qu'al gears '81 and 82,701 out "of mesh with either, for the purpose of changingthe'feedt, Thegears Stand-82 are mountedon a shaft 83which, bymeans of a worm 84drives "the'sl'e'eve '53 through a worm gear 8 5 on the sleeve.

It will'beseen therefore that the pinion i6 is operated by hand for "adj ustment or other purposes commoninthisindustry and'can be driven-by power to feed the tool "forward as it'rotates, and that the feedcan-be changed by adefinite ratio on the machine.

In theuse oft-he machine the wheel-set '15 is deposited by a era-neon the a'cks 16, if they are used,and they-are adjusted to the proper elevation and positioned. The cen ters 13 and 1 are moved forward in the manner that has been described'and the wheel set'accurately centered by them. The clamps 19arethen fixed and th'e opposite wheels can bebored at spots from each other, simultaneously, or the pins in position can be turned o'ffontheioutsi'de and these two opera tions can be carriedon at 'both ends'or one operation at one *end andthe other at-the other end. 7

The slide 44 isatljusted to the proper'post tionlaterally by the screw 40 andthe 'corre' spending slide 36 is adjusted vertically by the screw After adjustmentthe boring orturning'tools-at bb'tllBHClS feed inwardly at the same time and, asthe length of thesurface to befinished is substantially the samein both cases, the two operations willconsume about" thesame time and-be finished together.

This constitutes a compact, strong'and durable machine which, to perform the operat'ions described occupies very much less space than has been thought possible heretofore and involves economy in manufacture and upkeep. It can be used as an attachment for a journal lathe for thegpurpose of quartering and pin-turning by drawing backthe ihead stock 21IlCltflllSt-0Gl(w&llfl inserting these attachments between them. :The twoends of the machine: are substantially alike although having some differences. as has been stated. Theopera-torcanicontroteverything from the front and .ends andnever has to got-around to the back, while running the *machine.
